A rock song that goes "It's a party baby"
So, i remember it when I had myspace playlist (of course i lost it) So, i remember this song and video where they were in a kids birthday party, and suddenly there's the vocalist who starts singning "I's a party baby!"
I just remember he had long hair (and a bandana or similar) and then the song goes like "It's a scream baby!" (Not sure if the word was exactly "scream" tho) I tried to search by the lyrics but there only appear other songs like, rap and pop? It probably was between 2007-2009 but I'm not sure if the song is any older.
